Serial No. 659,984. Divided and this application August 23, 1933, Serial No. 686,442. In Great Britain March 12, 1932 2 Claims.

This invention relates to caulking, packing, lagging or covering and reinforcing material for use in making pipe and other joints, for jacketing, lagging and insulating pipes, tanks and the like, for use in brake linings, floor coverings,

moulded india rubber reinforcements, cable coverings, hose pipes, shoe soles and other purposes, in many of which cotton, flax or like vegetable fibres or animal fibres are at present employed.

This application is a division of my copending application, Ser. No. 659,984, filed Mar. 7, 1933.

The primary object of the present invention is the production of an inexpensive hard wearing material for a variety of purposes in which resistance to decay and unaffectedness at relatively high temperatures are of importance.

The present invention comprises the use of vegetable fibres carded, spun and woven into a material, treated with any suitable binding, plastic, protective or lubricating material and with or without a suitable filling material and formed into a material which is most readily used for its intended purpose.

In one embodiment of this invention, particularly adapted for use in caulking or packing the joints or flanges of pipes, or for use as a lagging or jacketing for pipes, tanks and the like, vegetable fibres such as sisal, hemp, or preferably coir or coco-nut fibre after extraction and in their natural state after extraction, which process is one in which the fibres are softened or entirely de-gurnmed by treatment with a neutralized sulphonated oil treated to an electric ionization process as described in my prior U. S. Patent No. 1,913,202 dated the 6th of June 1933, are combed, carded, spun and woven so as to produce a textile material. This textile material is then incorporated with any suitable binding, plastic, protective or lubricating material, for instance oil, bitumen, sodium or potassium silicate, calcium sulphate, alum or aluminium acetate, cement, gums, india rubber, powdered talc or plumbago. Such materials may be dissolved or mixed with any suitable liquid, into which the textile material is immersed, sprayed or otherwise treated, or alternatively the materials may be incorporated with the material in a dry state and subsequently treated with a liquid or solvent. After such treatment, the treated material may be rolled or pressed to exclude excess liquid and subjected to a heat treatment or vulcanization to mould it to a shape or form according to its intended use. In some cases a suitable filling material, such as cork or the fleshy matter from which vegetable fibres have been extracted, for example the pith surrounding coir, may also be incorporated with the fibrous mass before or after weaving.

It has been found that a material in which the basic component is softened coir, not only forms a highly resilient packing unaffected. by compression or by fluids, even superheated steam,

but also an efficient lagging for pipes and containers for insulating them from heat losses and is moreover very resistant to disintegration.

A woven material in which the basic material is softened coir can be usefully employed as a backing or cloth for floor coverings, for example linoleum, floor cloth and the like, and for such purposes has definite advantages over the usual hemp or jute backings at present employed.

The vegetable fibres-preferablycoirare extracted or treated and softened by means of a reagent (or an aqueous solution thereof) prepared by treating a neutralized sulphonated oil to an electric ionization and/or ozonization process. Coir so treatedmay be readily spun and woven into a relatively fine material which may be coated or impregnated with raw india rubber or india rubber mixture and afterwards vulcanized by heat.

In a further modification, the treated fibrous material may be Woven or braided to envelop a metal core of one or more strands of wire, alone or in combination with a mass of the unspun vegetable fibres. The product may be impregnated or compounded with a suitable binding,

protective, filling or lubricating material as hereinbefore described.

I declare that what I claim and desire to secure by Letters Patent is:-

l. A method of producing a material for use in caulking, packing, lagging or covering and for other purposes, consisting firstly in softening natural vegetable fibres and making them permeable to an agglutinating material by treating them with a reagent prepared by treating a neutralized sulphonated oil to an electric ionization process, secondly; carding the softened fibres, thirdly; spinning the fibres into yarn, fourthly; weaving the yarn to produce a textile material,

fifthly; immersing the textile material in a solution of agglutinating material, sixthly; compressing the material to exclude surplus solution and to mould it to shape according to its intended material by treating it with areagent prepared by a textile material, fifthly; immersing the woven treating a neutralized sulphonated oil to an elecmaterial in a bituminous solution, sixthly; rolling trio ionization process, secondly; carding the the treated material to remove excess solution, to softened coir, thirdly; spinning the softened coir compress it and to reduce its bulk, as set forth.

5 into yarn, fourthly; weaving the yarn to produce EUGENE VICTOR HAYES-GRATZE.
